Katie Price has had a difficult marriage to Kieran Hayler, after he admitted to cheating on her numerous times.

The mum of five is said to be worrying who she can trust after her husband’s numerous infidelities.

Kieran previously had an affair with Katie’s friend Jane Poultney. He also slept with their nanny Nikki Brown, something she denied until recently coming clean about their affair.

A source said: “Katie knows she’s being paranoid but she can’t help it.

“She looks at every woman that Kieran has any interaction with and thinks, ‘Will this be the next one Kieran sleeps with?’”

They continued to Closer: “She’s constantly making up conspiracy theories and if she even sees a pal’s hand brush against Kieran or a cosy-looking ‘hello’ kiss she’ll jump to conclusions and convince herself that he’s having another affair.”

They added that Katie recently accused her friend of having an affair with the former stripper when she spotted them laughing together.

“She quickly apologised and broke down crying,” they said. “But she’s not sure who to trust any more and is living on her nerves, which has worsened since Nikki’s admission.”

Nikki Brown denied she had ever slept with Kieran, but later reportedly confessed that the pair had sex “on three or four occasions”.

Nikki’s confession comes amid an employment tribunal, where she is reportedly claiming “thousands and thousands” of pounds from the Loose Women star in unpaid wages.

A source told The Mirror: “Nikki claims Katie owes her thousands of pounds, which Katie disputes.

“As part of the tribunal, Nikki is admitting for the first time that the affair took place, confirming they slept together on three or four occasions. It could be an explosive hearing.”
